Dalilah Muhammad dominated the Olympic women’s 400-meter hurdles in a blistering 53.13, ignoring a rain-soaked track and overwhelming a loaded field by almost a half-second to win gold Thursday in Rio de Janeiro.

As her parents Nadirah and Askia Muhammad looked on from the stands in Rio and a packed watch-party cheered back home in Queens, she did it in style, from the gun to the finish, bursting out of the blocks and never looking back.

“I was just happy it was over and relieved to come out with a win. I’m so thankful,’’ said Muhammad, who outpaced Denmark’s Sara Petersen and American Ashley Spencer.

“I didn’t know Ashley had got third at the time. That she made it too and became an Olympic medalist, I’m so proud of her and of myself. We’re making history out here, and I’m just so happy to be a member of that legacy.”

Whether she was referring to Team USA — her gold is part of their Olympic-leading 100th medal so far — or the track team, she was a big part of that history.

Muhammad became the first American woman to ever earn gold in the 400 hurdles, giving the U.S. a victory now in every single track event that requires blocks.
The 26-year-old Muhammad’s parents told NY1 this month that her Muslim faith — in conjunction with her natural ability and hard-earned discipline — got her to this point. That point is Olympic champion.

“A lot of people don’t realize how much work that goes into producing an Olympic athlete,” Askia had told NY1.

Muhammad began running as a little girl growing up in Rochdale Village. She started with the NY Novas running club at the age of 7, and by the time she had finished at Bayside’s Cardozo High School, she had won state, national and even a World Junior 400 hurdle championship before starring at USC.

But after earning silver at the 2013 World Championships in Moscow, she struggled through the next season — not cracking 58.0 once — and suffered an injury after last year’s Oxy Invitational.

Muhammad worked her way back, eventually left coach Yolanda Demus for Lawrence Johnson in February, and came through with a career season.

First came her brilliant performance at last month’s U.S. Olympic Trials in Eugene, Ore. — her career-best 52.88 was the fastest time in the world the past three years. She posted three of the world’s five fastest times this year, including 53.89 in the semifinals in Rio.

She blew that out of the water in Thursday’s final.

Running in Lane 3, she burst out of the blocks and made up the stagger on Denmark’s Peterson — one lane to her right — after just two hurdles. Intent on stealing the race quickly, and confident her training would hold up down the stretch, she was proven right on both.

Despite chopping her seventh hurdle as she came off the final turn, briefly giving Petersen the slimmest glimmer of hope, she snatched it away by easily holding her off.

“I felt really good. I wanted to get out like I normally do and stick to my race plan that I’ve been working on all year,’’ Muhammad said. “I had little hiccups in the race, but you have little hiccups in every race and no race is perfect. I just worked as hard as I could possibly work off the last hurdle.”

Peterson earned silver in 53.55, American Ashley Spencer bronze in a personal-best 53.72 and reigning world champion Zuzana Hejnova of the Czech Republic fourth, all roundly and soundly beaten by the hurdle queen from Queens.
